Specification of Letters Patent.

Patented Aug'. 27, 1907.

Application filed February 16,1906. Serial No. 301,459.

To all whom 'it rmay concern:

Y Be it known that I. JOHN E. NELsoN. a citizen of the Unite States, residing at Chicago, in the county of llooli and ffltatc of Illinois, have invented new and useinl improvements in SiphonSeparatorsoi which the following is a specication.

This invention relates to a siphon separator' or decanting device, particularly adapted for separating cream and milk as usually delivered in bottles, or for any other purposes to which it may be found applicable.

The improved Siphon separator' is simple and compact in forni and will be preferably constructed wholly of glass and has directly attached to the outlet extremity of the long leg thereof a pump device for starting the flow or creating the necessary suction in such leg. This pump device is disposed longitudinally with respect to the legs oi the siphon or main body of the device to facilitate an operation thereof without disturbing the applied position of the separator and in contradistinction to siphon devices of this class wherein a suction bulb or other pumping device is 'disposed in a plane at an angle to the legs.

The improved separator embodies means for readily adjusting the depth of penetration or submergenc'eof the shorter leg thereof with respect to the milk and cream or other liquid and to accommodate the use oi the device in connection with bottles or vessels varying in depth.4

ln the drawings7 Figure l is an elevation of a Siphon separator shown applied to a milk bottle and embody! ing the features of the invention. Fig. 2 is a section through the separator. -Fig. 3 is a detail elevation of the lower portion oi the short leg oi the Siphon illustrating slight modification.

Similar numerals of reference are used to indicate corresponding parts in the views. y

The numeral 1 designates the short leg. 2 the long leg. and 3 the elbow connecting the legs of the Siphon. At its'lower extreml y the long leg 2 is deflected at a downward angle of inclination, as at 4, to encourage an outf flow or to facilitate the operation of the siphon. In startingoperations the terminal of this downwardly de- '.ilected portion fl may be closed bya suitable stopper (not `listing a piston 7 therein provided with a piston rod 8 Y he lower end of the short leg I may be fully with its upper terminal projecting above the said body.

The disposition of the cylindrical body 6, or the pump v device as an entirety longitudinally with respect tothe long leg 2 of the siphon is materially advantageous in that such pump device may be more readily operated in starting the Siphon and also overcome anytendency of displacement oi the latter. o

The longitudinal disposition of the pump device or suction creating means just specified renders the coinplete separator compact in form and convenient in storage as well as in application. As shown it is preferred that the cylindrical body 6 have its lower end integrally formed with the downwardly inclined extremity 4 of the long legr 2, so that the separator as a whole'may be structurally completed at rone operation and without requiring connection oi the parts of the formation oi joints which would require packing or other treatment to render the same air tight Y' The separator embodies very simple means for regulating the depth of penetration or subinergence of the short leg I, and also controlling the application of the' separator to receptacles of varying depths. This regulating means consists of a surrounding band or strand 9 of suitable material which is adapted to be shiited longitudinally with respect to the legs l and 2 and be oi material oi' such nature as to naturally adhere to the legs, or frictionally engage the latter with suilicient re sistancc to avoid accidental displacement thereof. The advantages of this regulating means will be readily appreciated and in the use ther oi it bears on theriin o r upper edge oi the receptacle into which the short leg l is projected to carry on the separating or decanting operation. This regulating means has the further function of reinforcing the pump device and the longer leg ot' the Siphon. l

The short leg l is inserted in the milkbottlc or other device containing a liquid adapted to be separated, and after it is disposed in proper position the pump device is operated to create sul'licient suction iu the long leg2 to start the ilow of the liquid through tho Siphon and during such flow the pump device remains idle or is not opn erated unless there be a tendency to check of the ilow,

and if the lattercondition is present or apparent it can' be quickly modified and a regular flow caused by again actuating the pump device. suitable stopper may be inserted in the open end ofthe projection 4- in the starting operation, or the finger ofthe operator may be temporarily held against such open' end. As soon as the suction has been created in the long leg by the use ofthe pump device it will be understood that i1' a plug or stopper be inserted in the open As before indicated ai ond o the projection 4 such closing device will be immediately removed to avoid any obstacle to the free flow of the liquid through the long ieg 2.

What I claim is:

A separating device of the class set foi'th comprising n Siphon having two legs null :i pump connected with a pob tion of the longeileg' and in parallel relation to said Inner, and n device adjustnhly engaging the Siphon legs nml pump and opel-ating to regulate the depth of penetration of l'he upper leg with respect t0 the locality operated upon znd also reinforcing.:l the pump und .longer legof the Siphon adjacent to which the pump is located.

In testimony whereofy I -nflix my signature in presence of two lines-ses.
